1HZ TO 150KHZ PWM FREQUENCY GENERATOR MODULE

1Hz-150Khz Signal Generator PWM Board Module Pulse Frequency Duty Cycle Adjustable Module LCD Display 3.3V-30V 1Hz - 150Khz


Highlights
1 LCD display frequency and duty cycle, very clear, PWM output can be set separately frequency and duty cycle;
2. Wide frequency range, high precision;
3. It can use serial communication
 
Description
PWM output, you can set the frequency, duty cycle;
Frequency is divided into four ranges, automatic switching:
1. XXX (no decimal point): the smallest unit is 1Hz, the value range of 1Hz ~ 999Hz;
2. X.XX (decimal point in the hundred) the smallest unit is 0.01Khz, the range of 1.00Khz ~ 9.99Khz;
3. XX.X (decimal point in ten): the smallest unit is 0.1Khz; value range of 10.0KHz ~ 99.9KHz
4. X.X.X (decimal point in ten and hundred): the smallest unit is 1Khz; value range 1KHz ~ 150KHz
e.g. frequency display: 100 indicates PWM output 100Hz pulse;
                                   1.01 indicates PWM output 1.01K pulse;
                                   54.1 indicates that the PWM output has a pulse of 54.1 kHz;
                                   1.2.4 indicates that the PWM output is 124 kHz pulse;


Duty cycle range: 0 ~ 100%;
All set parameters, power down save.

Parameter settings
The module has four independent keys, used to set the frequency and duty cycle, support short press (increase or decrease a unit) and long press (fast increase or decrease), very simple, set the parameters automatically save, power failure Lost.
 
Module parameters
1. Working voltage: 3.3 ~ 30V;
2. Frequency range: 1Hz ~ 150KHz;
3. Frequency accuracy: the accuracy in each range is about 2%;
4. Signal load capacity: the output current can be about 5 ~ 30ma;
5. Output amplitude: PWM amplitude equal to the supply voltage;
6. Ambient temperature: -20 ~ +70 ℃.
 
Scope of application
1. Used as a square wave signal generator, generate square wave signal for experimental development and use;
2. Used to generate a square wave signal that controls the motor driver;
3. generate adjustable pulse for MCU use;
4. Generate adjustable pulse, control related circuit (PWM dimming speed and other applications)


Serial Port Control
Communication standards: 9600 bps data bits: 8
Stop bit: 1
Check digit: none
Flow control: none

1. set frequency of PWM
F101: set frequency to 101HZ (001 to 999)
F1.05: set frequency to 1.05KHZ (1.00 to 9.99)
F10.5: set frequency to 10.5KHZ (10.0 to 99.9)
F1.0.5: set frequency to 105KHZ (1.0.0 to 1.5.0)

2. set PWM duty cycle
DXXX: set PWM duty cycle to XXX: (001 to 100)
Such as D050, set PWM duty cycle is 50%

3.read the set parameters
Send a "read" string to read the set parameters.
Setup successfully return: Down;
Setup failed to return: FALL.
